LAWRENCE BENSON, OESPOKANE, wnsnmo'roip DISH-WASHING MACHINE.

To all whom itmay concern Be'it known that I, LAWRENC BENSON, a v

. citizen of the United States, residing at Spokane, in the county of Spokane and State of 'lVashington, have invented certain'new and useful Improvements in Dish-lVashing Machines, of which the following 'is aspecification,

One of-the objects of this inventionis "to provide a dish washing machine with dish supporting neans or trays formed in sucha manner as to permit the dishes to be loosely disposed thereon so as to avoid the necessity ofany kind 'of attaching means to anchor the dishes. 1

A further object of my invention is to provide dish supporting means of this char- .acter which will permit of the projection thereon of a cleansing liquid from of directions. a y

A :further' object of my invention is to provide a washing machine in which dishes of the bowl or tlireen type may be efiectively washed, and in thisconnection, the invention provides for stationary means adapted to a variety character, such stationarymeans being so dispose'dwith respect to the movable parts so as to present the exterior surfaces of this type of dish for projection thereon by the cleansing in motion. H

The device of my invention presents other features of novelty which will be more fully and which will be more piarticularlypointedw described by the accompanying drawings outin the appended claim.

Fig.2

As illustrated, 1, designates a casing which may be of cylindrical form, and in which a vertically disposed operating shaft 2," is

f mountedf The-shaft. 2, may be journaled at its upper end in a suitableflbearing 3, formed on top 4, of the casing '1. A lower bearing 5, is provided forthe shaft 2, and

[may be disposed onthe lower dish carrying" tray, if, desired. In order-toafiford access to the interior-of the casin "1, I provide the same with a door 6,.whic may be'hinged at. 7, ahd' secured by any suitable fastening v need be described in detail.

- device 8. On the 4, provide bearings 9 and 10, in which a crank shaft 11, is journaled. A crank,12,. is mounted on one end of said shaft, and the iotl1er;, end 'ofsaid shaft is geared to the operating shaft 2, by, r

l'Jevel-gears 13 and 14.

Near the lower end. of the casing provide a drainagebottom 15, which directs to a drain p1pe 1-6, ada ted for connection with the sewer or any ot 1er convenient receiving 7 I means for the water.

Upon the operating shaft 2,-and preferably in superposed, spaced, vertical relation, I mount apl'urality of dish supporting trays, all of which are the same inconstruction and operation, and only one ofwhich he trays are indicated at 17,18,19, 20, and 21,.and referrin'gto tray 17, it willbe seen that-the same consists of supporting frame 'bars 22,

mounted upon a hub 23, which latter is secured to the shaft 2, by means such as a set.

screw 24:. l The frame members 22, are inclined downwardly andoutwardly from the hub 23', to periphery of the tray, at which- In the present construction, the trays are sub:

stantially conical and ircular inform, and the tray frame, ust e'seribed, serves as a support 'for a reticulated covering 26, i on which the dishes are adapted to be disposed.

. The incline of the trays, together with centrifugal action resulting from the operation thereof, will serve to shift the dishes" outwardly against the rim 25, and when the tray is substantially covered with the dishes,

especially plates and' saucers of different sizes, they will interlock and beheld in'engagement with the edge of the'rim, in a most'efiective manner. Of course thesetrays will not be rotated at such speed as to cause the centrifugal action to throw the ,dishes outwardly over the rim 25.

Above'and below each; tray are disposed perforated pipes 27, 28, 29, 30, 31, and 32 and the pipes may be branched in U-shaped form, as indicated in Fig. 2." I preferably arrange the perforated pipeshorizontally so .that they will direct the streamsof cleansliquid angularly to the planes of the dishes" on the inclined trays, bothas regards the. upper and lower faces of the dishes Itwill thus be seen that by reason of the inclination of the dishes with respect to the streams projected thereon, I not only insurea eleansingaction throughout the area ofthe dishes. but I avoid the necessity of projecting the cleansing liquid thereon throughout theirtravel or rotation. and this, by reason of the. etl'cctive action of the streams of the cleansing liquid as htacinhefore stated.v I

The. pipes 2T toil) are connected to a manifold or main supply pipe 32-). which latter may he connected with an v' suitable source of supply of hot water. If it is desired to supply soap in liquid form I provide a cup 3L which may-he connected h v a pipe 35 to pipe 33.- I

In'rase it is only desired to use the upper t'a vs IT and 18. I provide a valve St). on the pipe 33. "which'mav he closed to cut oll' the. suppl of water from the pipes 31 aml $2.
